Opendtu / Ahoydtu Diy Kit
This DIY KIT is suitable for reading the data of a hymile inverter.
Communication with the Hymiles interverters takes place via 2.4GHz via radio. It is possible to access current values such as power, electricity, daily energy. Setting parameters such as the performance limit via web interface or MQTT.
The following Hymiles Referees are currently supported by Opendtu with the NRF24L01+ radio module: HM-300, HM-350, HM-400, HM-600, HM-700, HM-800, HM-1000, HM-1200, HM-1500
Further inverter supported by Opendtu: Solenso Sol-H350, Solenso Sol-H400, Solenso Sol-H800, TSUN TSOL-M350*, TSUN TSOL-M800*, TSUN TSOL-M1600*
*Note on TSUN compatibility: The compatibility with Opendtu is most likely related to the serial number of the inverter. Current findings indicate that TSUN inverters are supported with a serial number that begins with "11", while inverter is not supported with a serial number that begins with "10".
The optionally contained OLED Dispaly impresses with a high quality of representation. With the size of approx. 2.44cm, it has a resolution of 128 x 64 pixels. This shows texts and graphics with a high level of detail and sharpness.
With the I2C connection you can easily integrate the display into your DIY projects. Completely compatible with Arduino, 51 series, MSP430 series, STM32/2, CSR IC, etc.
This offer contains different variants to choose from:
Set + Opendtu Firmware = ESP32 Devboard including Opendtu Firmware + NRF24L01 + + Socket + 10cm Jumper cable
Set without firmware = ESP32 Devboard + NRF24L01 + + Socket + 10cm Jumper cable
Only ESP32 Devboard = only ESP32 board
Only NRF24L01+ & Socket = only radio module & socket
Only NRF24L01+ = only radio module
Only NRFL01 Socket = just socket
Only 0.96 inch OLED display = only 0.96 inch OLED display blue
only 10cm cable = only 10cm 8pin + 4pin jumper cable

Further information on license, firmware and installation:
No soldering required. Only the PIN cables have to be plugged together. Please note the facility instructions for initial commissioning. The display in particular must be activated with a configuration file.
A QR link or a link to the instructions are included in the form of an A6 flyer.
It is also possible to install Ahoydtu. However, this must be carried out itself. For more information, see link:
